1. Using a ½ " open-end wrench and two 5 ⁄
16
-18 x ½ " bolts, attach
bracket to actuator transfer case pads. Leave bracket loose to
allow for adjustment.
2. Using four ¼ -20 x ½ " bolts and a 7 ⁄
16
" open-end wrench, fasten
positioner to universal bracket, using the four-hole pattern that
locates the positioner the farthest from the valve. Rotate posi-
tioner 90 degrees from normal so gauges are facing upward.
3. Attach follower arm to positioner feedback shaft, using the star
washer and 10-32 nut.
4. Attach tripper and tripper clamp to valve shaft using two ¼ -20
bolts and two ¼ -20 locknuts. Leave tripper loose on shaft until
fi nal adjustment.
5. Thread ball joint linkage end to tripper and tighten (thread
locking compound such as Loctite is recommended to prevent
back threading). Adjust the length of tie rod so follower arm and
tripper rotate parallel to each other (the rod must be cut to the
desired length). Connect the other ball joint end to follower arm
using a star washer and a 10-32 nut.
6. Tighten bracket and tripper bolting.
7. Check for proper operation, note direction of rotation.
 WARNING: If rotating in wrong direction, serious dam-
age will occur to the positioner and/or linkage. Check
air action and stroke direction carefully before initiating
operation.
5.4 NAMUR Rotary Mounting
The Logix 3200MD includes an option for NAMUR Rotary mounting.
The NAMUR shaft option provides mounting to standard brackets
for valve automation. The NAMUR option is not recommended for
high performance valves since the normal alignment tolerances can
cause a degradation in valve performance. Care must be taken when
mounting the positioner using a NAMUR confi guration to prevent
damage to the shaft. Mount the positioner and rotate into position
using the following table:

5.5 Tubing Positioner to Actuator
The Logix 3200MD digital positioner is insensitive to supply pres-
sure changes and can handle supply pressures from 30 to 150 psig.
A supply regulator is recommended if the customer will be using
the diagnostic features of the Logix 3200MD but is not required. In
applications where the supply pressure is higher than the maximum
actuator pressure rating a supply regulator is required to lower the
pressure to the actuator’s maximum rating (not to be confused with
operating range). An air fi lter is highly recommended for all applica-
tions where dirty air is a possibility.
!
NOTE: The air supply must conform to ISA Standard ISA 7.0.01
(a dew point at least 18°F below ambient temperature, particle
size below fi ve microns—one micron recommended—and oil
content not to exceed one part per million).
Air-to-open and air-to-close are determined by the actuator tubing,
not the software. When air action selection is made during con-
fi guration, that selection tells the control which way the actuator
has been tubed. The top output port is called Output 1. It should be
tubed to the side of the actuator that must receive air to begin the
correct action on increasing signal. Verify that tubing is correct prior
to a stroke calibration. Proper tubing orientation is critical for the
positioner to function correctly and have the proper failure mode.
Refer to Figure 5 and follow the instructions below:
Linear Double-acting Actuators
For a linear air-to-open actuator, the Output 1 port of the
positioner manifold is tubed to the bottom side of the actuator.
The Output 2 port of the positioner manifold is tubed to the top
side of the actuator. For a linear air-to-close actuator the above
confi guration is reversed.
Rotary Double-acting Actuators
For a rotary actuator, the Output 1 port of the positioner manifold
is tubed to the bottom side of the actuator. The Output 2 port of
the positioner manifold is tubed to the top side of the actuator.
This tubing convention is followed regardless of air action. On
rotary actuators, the transfer case orientation determines the air
action.
Single-acting Actuators
For single-acting actuators, the Output 1 port is always tubed to the
pneumatic side of the actuator regardless of air action. The Output 2
port must be plugged.
